Abstract

Increased number of population participating in sports results in unavoidably increase of incidence of sports injury. It also causes a rise of total healthcare expenditure. Because the technology of a variety of imaging modalities and treatment for sports injury is rapidly developed, an up-to-date knowledge on technology is critical for the sports physician. Advances in areas of nuclear medicine, magnetic resonance imaging, ultrasonography, and multi-detector computed tomography, provides a variety of options to physician in the process of patient evaluation. Therefore, they should be aware of strength, limitation, indications, contraindications, and diagnostic accuracy of diagnostic tools.

Figure 1

A patient with calcaneal stress fracture. (A) A lateral foot plain radiograph shows no definite fracture line on calcaneus.

(B)Whole body bone scintigraphy shows increased uptake at right hind foot area.

Figure 2

A patient with intra-articular calcaneal fracture. (A) A lateral foot plain radiograph shows suspicious vertical radiolucent fracture line at calcaneal body. (B) Sagittal reformatted CT image clearly shows the fracture line extending to subtalar joint. (C) Three-dimensional (3D) image with surface shaded technique (SSD) shows multiple fracture lines at a glance.

Figure 3

A patient with full-thickness tears of supraspinatus tendon. Oblique sagittal reformatted (A) and oblique coronal reformatted (B) image of shoulder CT arthrography show contrast material which injected into glenohumeral joint traverse (arrow) the supraspinatus tendon (asterisk) and reach to subacromial-subdeltoid bursa (arrowheads).

Figure 4

A patient with complete tear of extensor pollicis longus tendon (EPL) A.

Transverse sonography at the level of distal radius shows empty right third extensor compartment (arrows). B. extended field of view image shows swollen distal part of EPL which disrupted at scaphoid level.

Figure 5

US guided subacromial injection procedure. Needle tip is located between mildly thickened subdeltoid bursal wall (arrowheads).

Figure 6

A patient with transient patellar lateral subluxation. (A) Patellar skyline view of right knee shows linear increased opacity parallel to medial patellar facet (arrow) representing osteochondral fracture fragment. (B) Transaxial image of saturated proton density weighted MR image shows subchondral bone marrow contusion at medial patellar facet and lateral femoral condyle (arrows) and osteochondral fracture fragment from medial patellar facet (arrowheads).

Figure 7

A patient of medial meniscus horizontal tear. Proton density weighted coronal (A), sagittal (B), and transaxial (C) images show intrameniscal linear high signal intensity area which extend to inferior articular surface (arrows in A and B, arrowheads in C), and multilocular fluid-like high signal intensity area representing parameniscal cysts (arrow in C).
